No. No. NO!!
Politics is absolutely NOT a secondary issue. Also, the issues that black people currently face will not be solved simply by business or capitalism.
Again you're practicing selective memory and not paying attention to history or context. Following emancipation, an entrepreneurial spirit was promulgated in the black community by various people (Booker T Washington being the most notable). Black people being the creative people they are hurriedly took to this and the end result was a proliferation of black owned businesses (i.e. insurance companies, banks, grocery stores, etc). Mind you this was back in the nineteenth century. NINETEENTH CENTURY! Just like all Americans, black people understand business and capitalism very well, there's no sort of handicap we're ailing from.
Unsurprisingly, all of these businesses ended up being failures, due to a combination of a lack of business acumen on the part of the blacks, and duplicity on the part of the liberal whites who were assisting with these ventures. This trend of start a business, bust, start another business, bust, has continued well into the modern day.
Also, if you think about it, Jim Crow unintentionally fostered an entrepreneurial spirit in southern black communities. The majority of stores servicing the segregated blacks were black-owned. This is good right? Nope. When you tallied the profits up, these stores were almost always doing worse than similar black-owned stores up north, where the POLITICS was different and segregation was not a concern.
I highly suggest you read Frazier's Black Bourgeoisie as it covers this topic in full, complete with hard data.
